HUNTINGTON, INDIANA MOTOR-PLOW.

in maar).

To .lc/mm /f/f/j/ fonce/*HJ Beit known that l. Cnuls'rmx F. l'liiiNSS, a citizen oiI the l'ulted States. and a resident ol Huntington. iu the county ot' lluntington and State oi' Indiana. have invented certain new and use'l`ul Improvements in M0- tor-llows` ol which the tollowing is a full, clear. and exact description. reference heilig had to tl f aeeomjmnying drawings, torining part o'l this specification.

M v invention relates to the class oi plows where digging tools are mounted in an endless chain or upon the periphery oi' a drinn so as to be successively brought into contact with thesoil to be cultivated and wliei'e the diggers travel considerably faster than the plow, somewhat aiter the lashion of a stern paddle steamboat.

Ithas as its object the providing oic a strong and economical means for mounting and operating the spades or diggers, and

p, simplicity oi structure so that operation is easy and that home repairing may be done readily.

'one ot' the chains aud stiil\'e.-otl' bars with the lower di'um in section. .Fig fl is a detail oi the worm and shaft i'or raising and lowering the plow traine. Fig. 5 is a perspecti ve view on a larger scale of one of the links and spades. Fig. G is a detail showing the arrangement of spades and plows at the base ol the machine.

,The frm/w uml Zei/)vlag ymemes-'fhecultivator comprises two frames 1 and 2, the

' former carrying the motor 3 and supported Ion an axle carrying the fore wheels 4, 4, and

the latter carrying the druins and chains which do the plowing or cultivating.

The machine has a central axle 5 on which vare journaled the hubs (3 ot' the driving Wheels 7. rFliese driwing Wheels have roughanedrinis to prevent slipping, and are internally toothed at 8. A pinion 9 on a shaft 1G meshes with this `internal gear so formed and the shaft is driven by means of the beveled gears .11 .and the driving shaft 12 of the motor 3, as is obvious. Journal boxes 13 for the traine 1, and 14 for the frame 2are mounted von theinain axle 5. The frame 1 Specication of Letters Patent.

has thus a support on two axles, while the traine 2 is'supported on but one. The trani; 1 has the inotor 3 superimposed upon it, and it has also upon it the driver`s scat 15. The

frames are preferably made ot' stout channel bars, as illustrated.

.The cultivator portions are mounted upon the back end of the machine on thc end 0f the frame 2. These portions must be lifted ,from Contact with' the ground to allow travdirection. A large segmental rack plate 16 'is mounted on the ends of the channel bars of the traine 2 at each side. A shaft 17 is mounted on `journals 18 bolted at the under side of the cross bar k22 of the'franie 1 (Fig. 4). Pinions 19, 19 are mounted on the ends` of this shaft to mesh with the racks 16,116. A worin gear 20 is mounted on this shaft so as to 'niesh with a worin 21, mounted on a vertical rod 23 journaled on the frame 1. A hand wheel 2l on this rod within convenient reach from Ithe drivers seat is einployed'by the driver to turn the worin, and hence the pinions 19 which torce up or down the rack plates. IThus a great strength is not required to alter the position of the cultivator parts with relation to the balance ot' the inaehine. rl`he driver has the control within easy reach and the adjustment tor,diiclgging may be quickly and accurately made.

A steering wheel 25, with steering rod 2G and knuckle 2T, of usual foi-'in is'provided for steering` the machine., Neither a clutch nor a dill'erential is shown, because these Aparts are not absolutely necessary and would `end of the frame to the hangers; give addiexpenditure of A tional strength. rl`he two drums are identical in shape, being hexagonal in cross sec tion, and provided with a number of circumferential series of yteeth 33, one series for each chain of spades as will be developed. The upper drinn 29 is theA only one that is driven, the lower one being an idler and turned by the spade chains. The upper drum is driven by means of sprocket. chains 34, passing over sprocket wheels 35,y 35, mounted on the shaft 36 of the drum, the sprocket chains being drivenby the gears 37,

i 37, 'on a s haft'38 journaled at 39 on the frame. A sprocket chain 4() driven by the sprocket 4l on the shaft l0 (which drives the wheels 7) drives this shaft 3S, in turn, working over the sprocket 42 thereon.

The spade chains are separate fi'om each other and any desired number such as ten of them may be used.. A series of teeth on each drum for each4 chain is'required. The chains aremade up 'of links 43, pinned or otherwise pivoted to each other. closed end of each link lis a vertical hook 44:, andto this hook is riveted a spade Ll. These sprocket chains are driven by the` upper l drum passing over the lower drum and'lat the bottom'of the movement of each link its .adhering to the spades which -are-removed. The mounting of these strikespade digsinto'the earth. If' no clearing means were provided, the chains would soon become so clogged up with dirt between theni as to interfere 4with `the work of the v'spades- Grass, sods,.weeds and such like 'would be carried around and around and accumulate rapidly. I therefore provide strike-off bars 46; s'o as to lie between each cllainand its adjacent ones, rear ends. As the spades pass the point of contact with the soil, their return movement brings each spade alongside of Y'a 'strikeolf bar traveling. at first 'parallel with it and then gradually down from it. Thus theinterchain space is cleaned and clods or sods are of any size off -bars comprises the upper angle bar 47 extending across and secured to the channel bars and the lower angle bar 48 secured across between the braces 32, spoken of in connection with the-hangers for 'the lower chain drum. The strikeof bars are secured to these cross bars by riveting their arms 49 thereto, at the proper points so that they lie in the interchain space.

To turn over the soil that is dug by the spades, I locate on the lower end of' each strike-ofi' 4ba'r a small plow' or mold board 50. These are riv ted on an arm 51, which is in turn riveted to the strike-olf bar. These plows also assist in the removal of dirt from the spades and chains.

The -machine will be so geared that the spade chains run faster than the driving wheels. thereby m'ving the necessary pursaid bars mounted and Haring downwardly at their.

The method of they will dig mounting'the parts of the machine onacentral and common axle,'and raising and lowering the entire cultivator frame from this position on the axle as a pivot, gives the desired adjustability for depth to the l lower chain drum, without strength and Again the cleaning or striking off of clinging sods, -weeds or clods enables the farmer to use this. cultivator on new land, For' in plowing under heavy growths.

sacrificing durability in any particular.

The spade chains being separate may be replaced without obtaining an Aentire newset, or shippingl away all the digging parts,

as is the case in such rotary diggers of the prior art.
